United States Patent 3,478,734 PORTABLE COOKING AND HEATING DEVICE IvanCovey, 5825 Denton Road, Belleville, Mich. 48111 Filed Oct. 13, 1967,Ser. No. 675,212 Int. Cl. F24c 5/02 U.S. Cl. 126-44 1 Claim ABSTRACT OFTHE DISCLOSURE This application discloses a portable cooking and heatingdevice, which employs liquid petroleum gas as the heat producing medium.The invention resides in a portable carrier frame having a table likeelement for mounting a stove, a platform for supporting a can of liquidpetroleum gas, and means to support the frame, including rotatable andheight adjusting elements.

This invention relates to cooking and heating devices and has particularreference to a device of that character, which may readily be used in atent, camper, cabin, boat,

trailer, apartment, home or other place, such as an openair campsite,which it is desirable and necessary to provide quick cooking or heatingfacilities.

An object of the invention is to provide an integrated, readilyportable, cooking device, which is simple in construction, economical tomanufacture and assemble, and efiicient in use.

Another object of the invention is to provide a device of the characterindicated which is compact and may be stored or used in a confinedspace.

Another object of the invention is the provision of a device of thecharacter indicated, which is constructed with a wheeled frame, having atable portion for supporting a tove, and a platform for supporting areceptacle carrying a supply of gas under pressure, and means forquickly connecting the gas receptacle to the stove.

Another object of the invention is the provision of a device of thecharacter indicated, which is constructed with a frame for supporting astove and a gas receptacle, said frame having rotatable elements thereonfor transporting it over a flat surface, and adjustable legs for raisingand lowering the rear portion of said frame when at rest.

The foregoing and other objects and advantages of the invention willbecome more apparent as the description proceeds, reference being madefrom time to time to the accompanying drawing, forming part of thewithin disclosure, in which drawing:

FIG. 1 is a perspective view of a device embodying the invention.

FIG. 2 is a side elevational view of the device shown in FIG. 1.

Referring now more particularly to the drawing, it will be understoodthat in the embodiment herein disclosed, the reference character 7indicates, in general, the carrier frame. The reference character 8indicates the stove support, and the reference character 9 indicates thegas receptacle support platform.

The frame 7 consists of a pair of vertical members 10 and 11, and atransverse member 12, which are preferably made of angle iron and aresecured to one another by welding or other suitable means.

The stove support 8 is preferably made of a fiat piece of heavy gagemetal, having upturned flanges 8A and SE at front and back respectively.The stove support 8 is welded, or otherwise secured to the frame 7, asat 8C.

The stove support 8 also may be used as a table when the stove isremoved.

The platform 9 is substantially rectangular in shape, and is made up offront member 13, rear member 14, side members 15 and 16, which arepreferably made of angle iron, and an intermediate metal bar 17, all ofwhich are secured to one another by means of welding, or other suitablemeans. The platform 9 is secured to the frame 7 by welding, as at 18(FIG. 1).

The frame 7, stove support 8, and the platform 9, are preferablyreinforced by cross members 19, 20, 21, and 22, which are welded, orotherwise secured at their ends, to the frame 7, the stove support 8,and the platform 9, as shown in FIGS. 1 and 2. The members 19, 20, 21and 22, may also be spot welded, as at 23, to provide further rigidity.

Secured to the underside of the frame 9, by any suitable means, is apair of brackets 24 (FIG. 2), which are bored to receive a shaft 25, onwhich is mounted a pair of rubber tired wheels 26, so that the assemblymay easily be transported from place to place.

The assembly is supported at the rear by a pair of threaded legs 27,which engage nuts 28, welded or otherwise secured to the frame 7. Withthe adjustable legs 27 the device may be made level on any type ofterrain. This is an advantageous feature of the invention, particularlywhen the device is used at a campsite or out-of-doors where the terrainis naturally uneven.

Mounted on top of the member 8 is a conventional gas stove 29 which mayhave at least two burners, which are controlled by the valve members 30and 31, as in conventional practice.

The stove 29 may be secured to the member 8 by any suitable means, or itsimply may rest on the member 8 and be held against forward or backwarddisplacement by means of the upturned flanges 8A and 8B. Of course, itis held, to a certain extent, against lateral displacement when it iconnected up, as hereinafter described.

Mounted on the platform 9 is a conventional liquid petroleum gasreceptacle 32, which is connected to the stove 29 by means of a flexibletube 33, and a coupling 34. The gas tank 32 is provided with aconventional pressure regulator 35 and a shut-off valve 36. The tank 32is held against displacement on the platform by means of a metal strap37 which encircles it, the ends of which strap are bent outwardly, as at38, and are bored to receive bolts 39, which extend through the boresand through similar bores in the frame member 12.

The gas tank 32, which is normally charged with sufiicient gas tooperate the stove 29 over an extended period of time, is readilyobtainable on the open market. The tank 32 is preferably left on theplatform 9 at all times while there is any charge left in the tank, andmay be readily replaced by another when the charge has been exhausted.

It is believed that the operation of the device is obvious from theforegoing description.

Having described my invention, what I claim and desire to secure byLetters Patent is:

1. A portable cooking device of the character described comprising thecombination of a wheeled frame having upper and lower platforms, theupper platformhaving received thereon a cooking element, with means toanchor said cooking element against displacement, the lower platformhaving received thereon a tank of liquid petroleum, which tank issubstantially co-extensive with the area defined between said upper andlower platforms, and

3 4 means communicating the said tank with said cooking 2,900,897 8/1959Fisher 126-9 X element. 3,210,537 10/1965 Groves 12644 X ReferencesCited FOREIGN PATENTS UNITED STATES PATENTS 5 1,088,794 9/1954 France.3,140,740 7/1964 Lagreid et a1 625O 1,040,451 10/ 1912 Stockton 126276EDWARD G.
